A wastewater treatment plant that treats wastewater to secondary treatment standards uses a primary sedimentation process followed by conventional activated sludge process composed of covered aeration tanks and secondary clarifiers. You are asked to calculate the different operation parameters to make sure that the system is operated within normal process ranges listed in the reference tables below. Table 5-20 Typical design information for primary sedimentation tanks U.S. customary units Item Unit Range Typical Primary sedimentation tanks followed by secondary treatment...

Describe in detail the function of the wastewater treatment plant components below and what stage of treatment they are (primary, secondary, tertiary) use the lines provided for the second part of this question. For the descriptions use any space on the next page. In the descriptions you must state what is specifically being treated, and if compounds are generated in a particular treatment stage you must describe that as well. In addition, if a particular process has two stages -...

Given: There is a wastewater treatment plant that has a Primary Clarifier, Activated Sludge, Secondary clarifier and the average daily flow was 1 mgd. Calculate the volume needed if the activated sludge is 24 hours 10 Mgal 100 Mgal 1 Mgal 1000 Mgal

T/F (true/false) Wastewater Treatment A principle objective of the conventional activated sludge process is to lower BOD. During the conventional activated sludge process, ammonium is converted to nitrate. A key requirement of the conventional activated sludge process is that it be carried out under strictly anaerobic conditions. In typical systems, denitrification occurs in an aerobic step after the activated sludge step. In the Modified Ludzak-Ettinger (MLE) process (and its variants), "mixed liquor" from the end of the aerobic step is...

this is an environmental microbiology question. i’m studying the wastewater treatment. I’m really confused and my question is : can sewage treatment and waste water treatment be considered the same thing? Also, when describing anaerobic and aerobic treatment do they happen both during the sewage treatement process or if one happend there’s no need for the other one? also, the primary sludge is it further purified by the secondary treatment or is it removed?

2. [20] A small town has been directed to upgrade its primary wastewater treatment plant to a secondary plant that can meet an effluent standard of 25.0 mg/L BODs and 30.0 mg/L suspended solids. They have selected a completely mixed activated sludge system. The following data are available from the existing primary plant. Existing plant effluent characteristics Flow = 0.2000 m 3/s soluble BODs-80 mg/L Assume that the BOD5 of the suspended solids may be estimated as equal to 50%...

1. Contrast the structure and function of myoglobin and hemoglobin. Describe the primary, secondary, tertiary and quaternary structure of both proteins. Describe their motifs and domains if appropriate. 2. How similar are the mammalian hemoglobin and myoglobin (in terms of amino acid composition)? 3. Recall the functions and structure of leghemoglobins, chlorocruorins, hemerythrin and hemocyanin. In what organisms are those proteins found? How are this globins different from mammalian globins? 4. Not all O2 molecules bind to each of the...
